Scalp Psoriasis. It is generally believed that psoriasis comes about as a combination of genetic, immune and environmental causes. It also has a tendency to run in families. Severe scalp psoriasis sometimes warrants treatment with tablets or injections such as methotrexate, ciclosporin, Acitretin or biologic agents. Patients should be under the care of an experienced dermatologist.
